ok i really dont mean to be a post whore, im not trying to be. anyway, my throwout bearing talks to me a lot. it talks to me in gear while accelerating, and out of gear in neutral. however, i can make it shut up by putting my foot all the way down on the clutch pedal. a dealership mechanic mistook the bearing noise for a bad timing chain its so loud. but as i said once the clutch pedal is 100% depressed, the engine is quiet and the throwout bearing stops talking. well, escept for the fan clutch, but anyways. the bearing doesnt talk to me, thats the most important thing. is there anything i can put in the transmission or hydraulic fluid container to quiet the bearing down? i know the clutch is still good because it grabs very well, i dont smell any clutch period, and it still can burn out very hard. any ideas?

No, man.....there really isn't. The clutch fluid and gear oil never touch the throwout bearing. It's entirely seperated from the two. It rides on the input shaft of the transmission inside the bellhousing. However, your noise is not the throwout bearing from the way you describe it. If it were, you'd hear it when you begin to press in. Were it the pilot bearing, you'd hear it when you press all the way in. What is sounds like is the input shaft bearing. In which case, you might check your fluid level and look to see if your leaking oil from the shaft seal. Peek into the bellhousing through the clutch fork entrance....if you can. It's a tight predicament in there.

I agree sounds like input bearing on trans. Once the input shaft stops from depressing the clutch pedal the noise goes away. This is the weak point on Toy manual trans.

PS get yourself a new Mechanic.

When I had the original clutch and T/o bearing in my 88' it didn't do any "talking" but with the new Centerforce II clutch and centerforce T/o bearing it talks more.It is most notice able in drive thrus. It works fine though.
Hope this makes you feel better.

haha. ok so the input shaft bearing. great... lol. do i gotta drop the trans to replace that? and flash, i dont believe i said anything about my mechanic... why should i get another one?

I think it's because he told you the t/o bearing.

Which is funny because thats what my mechanic told me about mine and it only talks when you are letting out the clutch pedal.

he didnt tell me that, i guessed thats what it was since it had to do with the clutch. lol. what mine told me was that hes heard them rattling both ways - clutch in and clutch out.

"a dealership mechanic mistook the bearing noise for a bad timing chain its so loud."
Sorry maybe not your mechanic but whoever told you this should find a new job. Cheapest thing to do is put some very good synthetic 75/90 in the trans and drive it until you can't take the noise anymore or it starts jumping out of 1st and 5th and then swap in a new trans. They can be had (used)for $150-200. Just check the endplay on the input shaft before you buy it. By the time you pull the trans apart to change the bearing and the bitch of a time you will have getting it off the shaft you will have paid for the other trans. IMHO. (I know from experience).

A good way to tell if the input bearing is going is listen for the noise to get quiet when you are in 4th gear and loudest in 1st and 5th. You are not putting torque through the driven shaft in the trans in 4th so there is less side load on the main shaft so the bearing will be quieter.

so it will be loudest in 1st and 5th? the tranny has been NOISY in 5th for the past couple years, and lately the rest of them are a bit noisy. so what you guys said about the input shaft bearing x2. i also found some rattling in the transfer case when the engine is revved in neutral. looks like im gonna have to change the chain in the transfer case... lol. anyone want to help? ill buy some beer and food.. lmao
